docker - 如何在本地 kubernetes 上使用 Kaniko

Question

我在 docker for windows 上使用 kubernetes。
我想使用 Kaniko，但我无法在本地 kubernetes 上构建图像。

Dockerfile

FROM ubuntu:18.04
RUN apt update
RUN apt install -y ssh

kanikopod.yaml

apiVersion: v1
kind: Pod
metadata:
  name: kaniko
spec:
  containers:
    - image: gcr.io/kaniko-project/executor:latest
      args: 
      - --dockerfile=/mnt/Dockerfile 
      - --context= /mnt
      - --no-push
      name: kaniko
      command:
        - sleep
        - infinity
      volumeMounts:
        - mountPath: /mnt
          name: mount-volume

  restartPolicy: Never
  volumes:
    - name: mount-volume
      persistentVolumeClaim:
        claimName: kaniko-workspace

但是发生了 ContainerCannotRun 错误。

kubectl describe pods kaniko
结果是

kubectl logs kaniko
但是没有输出。

我认为 kaniko 需要“--destination=”选项，但我找不到信息。
我应该怎么办？
